Free Minecraft calculators
Small tools for the sums every player ends up doing on paper. They run entirely in your browser — nothing is uploaded, nothing needs an account, and they work on a phone.
Nether Portal Calculator
Convert Overworld coordinates to Nether coordinates (and back) so your portals link exactly where you want them.
Stack Calculator
Convert any item count into stacks, chests, double chests and shulker boxes — and the other way round.
XP & Level Calculator
Work out how many experience points any level needs, the XP between two levels, and what a bottle of enchanting is worth.
Pixel Circle Generator
Generate a block-by-block circle or ellipse of any diameter for towers, domes, ponds and round bases.
Minecraft Time & Tick Converter
Convert game ticks to real seconds, Minecraft days to real hours, and read what any /time value means.
Coordinate Distance Calculator
Distance between two sets of coordinates, the direction to walk, and how long it takes on foot, by boat, horse or elytra.
How these tools work
Each tool implements the game’s real formula rather than an approximation. The Nether portal calculator uses the 1:8 coordinate ratio and the same rounding the game applies when it searches for an existing portal. The XP calculator uses the three-part level formula from the game code, which is why level 30 needs 1,395 points but level 15 needs only 315. The circle generator uses the midpoint algorithm most builders use by hand, so it produces the same shapes you would get from a careful template.
If you spot a result that does not match what the game does, tell us — include the numbers you entered and the version you are on and we will check it against the game.
